PATENT GFFICE SCRUBBER Application December 12, 1931, Serial No. 580,604

1 Claim.

Objects of the present invention are to provide for efliciently andthoroughly scrubbing air and gas containing dust particles, obnoxiousfumes and absorbable vapors; to avoid the development of resistance whengases are passed through the scrubber; and, in fact, under certainconditions, to actually create a slight draft; to avoid by-passing thegas in respect to the spray from the nozzles and to compel the gas topass through adjutages, or specially constructed throat pieces, whichare completely filled with spray issuing from jet nozzles; and to scrubthe gas by the impact action of spray from the spray nozzles.

Other objects of the invention will appear from the followingdescription at the end of which the invention will be claimed.

Generally stated, the invention consists in an upright casing havinghorizontal imperforate partitions subdividing it into superposedcompartments and having an inlet at its upper part and an outlet at itslower part, adjutages extending through and above and below thepartitions,

and spray nozzles directed towards the adjutages and adapted to ll thesame with spray.

The invention also comprises the improvements to be presently describedand iinally claimed.

In the following description reference will be made to the accompanyingdrawing forming part hereof and in which Figure 1 is a verticalsectional View showing diagrammatically a scrubber embodying features ofthe invention, and

Fig. 2 is a similar transverse sectional plan view.

In the drawing, 1 is an upright casing or tower. 2 indicates horizontalimperforate partitions subdividing the casing into superposedcompartments or spaces. 3 is an inlet at the upper part of the casing 1,and 4 is an outlet at the lower part of the casing 1. 5 indicatesadjutages inserted into the partitions and extending through and aboveand below the partitions. The cross section of an adjutage is generallycircular and longitudinally the cross section approaches two frustums ofcones with their smaller bases in contact. An adjutage is sometimesreferred to as a Venturi tube or nozzle and an adjutage and a Venturitube operate in much the same way. 6 indicates liquid spray nozzlesdirected towards the adjutages and adapted to ll the same with spray. 7represents holders shown as rectangular fish plates and they are a meansfor mounting the adjutages through the partitions. The throats of theadjutages are shown as aligned with the partitions, and the inlets oithe adjutages are shown as extending further above the partitions thanthe outlets of the adjutages extend below the partitions. The adjutagesare shown as arranged in staggered relation at the different partitions.

The mode of operation may be described as 50 follows: y

The air or gas to be scrubbed passes down through the scrubber, and theadjutages and sprays operate in such a way' that no resistance isdeveloped, and in fact under certain conditions 05 of operation, aslight draft is created. No gas can by-pass the range of the sprays,because the imlperforate portions of the partitions block it. The

gas or air can therefore only pass through the adjutages which arecompletely lled with spray issuing from the jet nozzles 6, and theimpact action of the spray eiliciently scrubs the gas or air.

It will be obvious to those skilled in the art to which the inventionrelates that modiiications may be made in details of construction andarrangement and matters of mere f orm without departing from the spiritof the invention which is not limited tosuch matters or otherwise thanthe prior art and the appended claim may require.

I claim: 50

A scrubber comprising, in combination, an upright casing havinghorizontal perforate partitions constituting the sole means forsubdividing it into superposed compartments and having an inlet at itsupper part and an outlet at its lowerV part, each of said partitionshaving adjutages extending through and above and below it, the throatsof the adjutages being aligned with the partitions and the inlets of theadjutages extending further above the partitions than the outlets of theadjutages extend below the partitions, and liquid spray nozzles directedtowards the adjutages and adapted to ll the same with spray, saidadjutages being arranged in staggered relation at the differentpartitions and suiiiciently95 spaced to spread the spray across thecompartments.
